Would this benefit me?

I was just thinking....of coures, its late, so im not doing it too well...would it benefit an athlonxp to run at say...235fsb with the ram at only 200? If its in dual channel? I would try it, but my mobo is out for rma right now. If you did this, you could get killer timings, high fsb, and actualy benefit from dual channel. it helps intel, so why not amd? Or does amd's shorter pipe not benefit so much from this?

It depends on your chipset- If you're running Nforce2 then it's always best to run in synch, with via you should just have the ram as fast as possible (e.g. 166mhz fsb, 200mhz memory). I don't know exactly why, maybe check out nforcershq.com forums for an explanation on the Nforce2.

You're better off running the ram at its maximum speed (at CAS 2.0 timings) synchronous with the fsb and adjusting the multiplier.

Hmm, well I thought since my ram cant go that high I could get a killer fsb if I ran out of sync. At the same time Im running dual channel, so that would help too.

Dual channel 400 mhz. That has double the bandwith, but not double the speed. The cpu would be starved for fsb time becasue even though it is dual channel, it is still slower then a real 800mhz memory. Dual channel widens the path for memory, it doesnt increase speed. 235FSB and 400Mhz dual channel would not perform as well as 200fsb and 400 dual channel. The cpu is not starved for bandwith, and that is all that dual channel adds. The cpu is simply starved for raw mhz.

This is different for intel, as their cpu is starved for bandwith, thats why 800 fsb and dual channel memory is like 50% faster then 533fsb in some cases.
